Suma:
Munyika yemapaipi esimbi,pombi yakasungirirwa yakatendererainozivikanwa nekuda kwesimba rayo repamusoro, kushanduka-shanduka uye kushanda kwayo zvakanaka. Mapaipi aya anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana akadai semafuta negesi, kutapurirana kwemvura, mainjiniya ekuvaka uye kuvandudzwa kwezvivakwa. Kuti tive nechokwadi chekubatanidzwa zvakanaka uye kushanda zvakanaka, zvakakosha kunzwisisa zvirevo zvinotonga mapaipi akasungirirwa espiral. Mublog rino, tichaongorora zvinhu zvakakosha zvemapaipi akasungirirwa espiral, tichijekesa saizi yawo, zvinhu uye zvinodiwa chaizvo.
1. Saizi yepombi:
Mapaipi akasungirirwa anotenderera anowanikwa muhukuru hwakasiyana-siyana, zvichiita kuti zvienderane nemapurojekiti akasiyana. Zviyero zvinowanzo sanganisira dhayamita yekunze (OD), ukobvu hwemadziro (WT), uye urefu. Dhayamita yekunze inotangira pamainji makumi maviri kusvika pamainji zana nemakumi maviri, uye ukobvu hwemadziro hunotangira pamainji mashanu kusvika makumi maviri nemashanu. Panyaya yehurefu, zvikamu zvakajairika zvemapombi akasungirirwa anotenderera zvinosvika mamita matanhatu, mamita masere, uye mamita gumi nemaviri kuti zvienderane nezvinodiwa zvakasiyana-siyana zveinjiniya.
2. Zvishandiso:
Kusarudzwa kwepombi dzeSSAW kwakakosha uye kunoenderana nekushandiswa kwaunoda uye mamiriro ekunze. Simbi yekabhoni inoshandiswa zvakanyanya nekuda kwesimba rayo, kugara kwenguva refu, uye kuramba ngura. Pamusoro pezvo, kune mamwe mashandisirwo anoda kuramba ngura zvakanyanya kana kuramba kupisa kwakanyanya, mapaipi akagadzirwa nesimbi ye alloy, simbi isina ngura, kana zvimwe zvinhu zvakakosha zvinogona kushandiswa.
3. Maitiro ekugadzira:
Pombi yakasungirirwa inotenderera inogadzirwa kuburikidza nemaitiro ekugadzira spiral uchishandisa simbi strip coils. Nzira iyi inoita kuti ukobvu hwemadziro, dhayamita uye chimiro chayo chifanane. Coil inopinzwa mumuchina, iyo inoiumba kuita chimiro chespiral chaunoda uye yobva yabatanidza mipendero pamwe chete. Tekinoroji yepamusoro inobatanidzwa mukugadzirwa kwayo inobvumira kudzora kwakanyatsojeka pamusoro pehukuru uye mashandiro epombi yekupedzisira.
4. Mitemo yemhando yepamusoro:
Kuti zvienderane nezvinodiwa neindasitiri uye kuve nechokwadi chekuti mapaipi esimbi akavimbika, matanho akasiyana-siyana ekusimbisa hunhu anoshandiswa. Izvi zvinosanganisira kutevedzera mitemo inozivikanwa pasi rose yakaita seAPI 5L, ASTM A252 uye ISO 3183-3. Kutevedzera mitemo iyi kunovimbisa hunhu hwemuchina, kuumbwa kwemakemikari, uye kururama kwepombi.
5. Kuedza nekuongorora:
Kuti pave nechokwadi chekuti pombi dzakasungirirwa dzakasimba uye dzinoshanda zvakachengeteka, panodiwa nzira dzakasimba dzekuongorora nekuongorora. Shandisa nzira dzekuongorora dzisingakuvadzi dzakadai sekuongorora kwe ultrasound, kuongorora kwe radiography uye kuongorora kwemavara. Miedzo iyi inoona chero zvikanganiso zvemaumbirwo kana kusawirirana kwezvinhu zvinogona kukanganisa mashandiro uye kugara kwenguva refu kwepombi. Pamusoro pezvo, miedzo yepanyama yakadai seye hydrostatic inoitirwa kuongorora simba uye kugona kwekutakura kumanikidzwa kwemapombi.
Mukupedzisa:
Mapaipi akasungirirwa anotenderera anopa mabhenefiti akawanda kupfuura mamwe marudzi emapaipi uye magadzirirwo awo anoita basa guru mukuchengetedza hunhu hwawo, kuvimbika uye kuenderana nemashandisirwo akasiyana. Kunzwisisa saizi, zvinhu, maitiro ekugadzira uye mwero wehunhu hune chekuita nemapaipi akasungirirwa anotenderera kwakakosha pakuona kushanda zvakanaka uye mhinduro isingadhuri. Sezvo tekinoroji ichiramba ichifambira mberi, magadzirirwo anodzora mapaipi aya ari kuramba achivandudzwa, zvichiwedzera kushanda kwawo uye kushanduka-shanduka mumaindasitiri akasiyana-siyana. Nekufunga nezvemagadzirirwo aya, mainjiniya nenyanzvi vanogona kuita sarudzo dzakarongeka maererano nekusarudza nekushandisa mapaipi akasungirirwa anotenderera kumapurojekiti avo.
